A triangle has side lengths of 7x - 4 and 3x + 2. If the perimeter of the triangle is 15x - 6, what is the side length of the third side?

Step-by-step explanation:

length of the third side = Perimeter - ( sum of the length of other two sides}

=15x - 6 - ( 7x-4+3x+2)

=15x-6 -(10x-2)

=15x - 6 - 10x + 2

= 5x - 4

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17
